To those of us who have horrible audio problems under 2008 Server by default (crackling, skipping, hissing, etc) and it worked fine in Vista, consider making the following registry change:

Key: HKLM\Software\Microsoft\Windows NT\CurrentVersion\multimedia\SystemProfile

Value: SystemResponsiveness

Type: REG_DWORD

Radix: Decimal

Data: 20

This makes Server 2008 behave more like Vista SP1 when scheduling CPU for audio/multimedia threads.

do I need to use a qword if I'm running 64 bit? (dword is 32, qword is 64)

Nope, it is a REG_DWORD value.

It's already present, so this is an edit, not a creation.

It is a good tweak, and does indeed work. After restarting, I no longer had a tiny pause/pop when ALT+TAB between programs while playing WMA music. Cheers!
